This Standard sets out procedures for the microbiological examination of sweetened condensed milks and recombined sweetened condensed milks, flavoured and unflavoured.

This Standard sets out procedures for the microbiological examination of sweetened condensed milks and recombined sweetened condensed milks, flavoured and unflavoured.NOTE: The methods are not intended for the examination of long shelf-life dairy products in hermetically sealed containers which may have been produced by the traditional canning process or by UHT processing followed by aseptic packaging. Such products are covered by AS 1766.3.16.
